Description

The PerkinElmer family of large-area InGaAs PIN photodiodes provide high responsivity from 800 nm to 1700 nm for applications including optical power meters, fiber optic test equipment, near-IR spectoscopy and instrumentation. All devices are planar passivated and feature low capacitance for extended bandwidth, and high shunt resistance for maximum sensitivity. Typical devices feature <1% non-linearity to optical powers >+13 dBm (20 mW), and uniformity within ±2% across the detector active area. Typical responsivity of 0.2 A/W at 850 nm for our large-area InGaAs devices allows use of a single detector in fiber optic test instrumentation designed to operate at 850, 1300, and 1550 nm.
